💅 show_wakeup_protocols(9) 💅

okay bestie, welcome to the Kernel API Manual corner of the group chat. this page is literally about the wakeup IR protocol, and we're keeping every single detail, no cap. 🫶

🌸 NAME 🌸

show_wakeup_protocols — shows the wakeup IR protocol. periodt. 💖

✨ SYNOPSIS ✨

ssize_t show_wakeup_protocols (struct device *device , struct
       device_attribute *mattr , char *buf );

🎀 ARGUMENTS 🎀

• device — the device descriptor. main character device energy. 🦋
• mattr — the device attribute struct. yes, mattr, we see you. 👀
• buf — a pointer to the output buffer. it's giving output buffer, bestie. ✨

💖 DESCRIPTION 💖

okay so this routine is a callback routine for input read the IR protocol type(s). it is triggered by reading /sys/class/rc/rc?/wakeup_protocols — yes, with the ? and everything. 👑

It returns the protocol names of supported protocols. the enabled protocols are printed in brackets. brackets!! that's the whole vibe check. 🎀

dev->lock is taken to guard against races between store_wakeup_protocols and show_wakeup_protocols. race protection is locked in, no cap. 💅
